A consumer television show I just saw talked about the use of urea- formaldehyde insulation during the 70s. The levels of formaldehyde can reach several times the safe level in poorly ventilated (that is, well-insulated) homes. However, the formaldehyde eventually leaches out of the insulation, and the levels produce decrease by about 50% each year (that is, a 1 year half-life). The show implied that after about 7 or 8 years, the insulation was pretty well "dried out" and no hazard existed. Mike Gray, BTL, WH.
